[Zope-dev] problems setting up methods for a product that registers no classes
...zdb in this case.
I need to make a global recompile function available, since zdb
requires the co_filename attribute of the script's func_code object to
be set to something meaningful, rather than the useless Script
(Python) it usually gets set to.
Once zdb is installed, any scripts editted will have this set, but I
wanted to provide a utility method in a similar vein to python scripts'
recompile function that could be globally accesed, however since zdb
registers no classes, I ended up having to do some fairly horrific
stuff, the following code is from zdb's __init__.py:
# recompilation utlitity
def initialize(context):
# This horrificness is required because Zope doesn't understand the
concept
# of a Product that doesn't register any classes :-(
pack=context._ProductContext__pack
fd=getattr(pack, '__FactoryDispatcher__', None)
if fd is None:
class __FactoryDispatcher__(FactoryDispatcher):
Factory Dispatcher for a Specific Product
fd = pack.__FactoryDispatcher__ = __FactoryDispatcher__
if not hasattr(pack, '_m'): pack._m=fd.__dict__
pack._m['debug_compile'] = debug_compile
pack._m['debug_compile__roles__'] = ('Manager',)
Now, this breaks in 2.8, so what SHOULD I be doing to make a method
globally available in a way that works in both 2.7 and 2.8?
cheers,
Chris

[Zope-dev] Broken objects
Hello zope-dev!
http://www.zope.org/Collectors/Zope/1911
I try to migrate my old database from zope 2.6.1.
I have Broken objects, but it is impossible to get its state in Zope 2.8.
In Zope 2.6 Broken objects have states, what i uses to migrate its.
I think this is because DB.classFactory is overrided to use
OFS.Uninstalled.BrokenClass, which is bad persistent class.
the __dict__ of all my Broken objects equals to {'_p_changed':None}.
my_object._p_mtime does not load it`s state.

I'll look into this. The first step will be to write a test for this.
The intent was definately that you would be able to get to a broken object's

I'm not sure what was happening with state in Zope 2.7, despite the
fact that I wrote that code. It would be helpful if you could
remind me what the behavior was.
In Zope 2.8, which is to ay ZODB 3.3 and later, the intent is that the
broken objects should provide access to the original state via
the attribute __Broken_state__. I guess this state isn't being
loaded. I'll write a test and fix as necessary to make sure it is.

[Zope-dev] Strange security issue with Zope 2.8.1
I have found a strange security issue with Zope 2.8.1 that seems to stem from code not doing what it was supposed to do in Zope 2.7.x, but which works in 2.8.1 and then causes other side effects in code that relied on the broken behavior. Symptom: In Zope 2.8.1 it is *impossible* to override a ClassSecurityInfo security declaration in an Archetypes-derived content item. (I have a small set of unit tests that proves the behavior under Zope 2.8.1 if anyone is interested) A little background: When you register an Archetypes-derived content type, it will do all the generated accessor/setter method magic and then call InitializeClass a second time. The code in lib/python/App/class_init.py has changed between Zope 2.7.x and Zope 2.8 in order to support new-style classes. To be more precise, instead of manipulating the class __dict__ directly we now use setattr/delattr/etc. This change seems to have un-broken code which did not do what the code comments suggest. Namely, when a class is sent through class_init.default_class_init__ (better known as Globals.InitializeClass) the class __dict__ is searched to find objects that look like ClassSecurityInfo instances in order to read and apply the security settings. After finding the ClassSecurityInfo instance, it is force-deleted from the object (the comments say, out of paranoia). However, somehow this did not work correctly in Zope 2.7.x, where the deletion call looked like... del dict[key] (dict being the class __dict__, and key being the name of the ClassSecurityInfo instance). Under Zope 2.8, it looks like this: delattr(self, key) (self being the class object). Under Zope 2.7, the security object *would still be there* when hitting InitializeClass for the second time via Archetypes' registerType, which in turn meant Archetypes would not instantiate its own ClassSecurityInfo instance and stuff it with the declarations from whatever Archetypes-derived base class you used. In Zope 2.8, the deletion actually works as intended - but due to that fact Archetypes will instantiate its own ClassSecurityInfo and populate it with the declarations from the base class that I am trying to override. So the overridden settings are all overwritten again by the base class declaration. My question is, what is the reasoning behind deleting the ClassSecurityInfo object from the class after it has been read the first time? How can this be implemented in a sane way so that custom security declarations can be retained? jens ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

The code in lib/python/App/class_init.py has changed between Zope 2.7.x and Zope 2.8 in order to support new-style classes. To be more precise, instead of manipulating the class __dict__ directly we now use setattr/delattr/etc. This change seems to have un-broken code which did not do what the code comments suggest. Namely, when a class is sent through class_init.default_class_init__ (better known as Globals.InitializeClass) the class __dict__ is searched to find objects that look like ClassSecurityInfo instances in order to read and apply the security settings. After finding the ClassSecurityInfo instance, it is force-deleted from the object (the comments say, out of paranoia). However, somehow this did not work correctly in Zope 2.7.x, where the deletion call looked like... del dict[key] (dict being the class __dict__, and key being the name of the ClassSecurityInfo instance). Under Zope 2.8, it looks like this: delattr(self, key) (self being the class object). Under Zope 2.7, the security object *would still be there* when hitting InitializeClass for the second time via Archetypes' registerType, which in turn meant Archetypes would not instantiate its own ClassSecurityInfo instance and stuff it with the declarations from whatever Archetypes-derived base class you used. In Zope 2.8, the deletion actually works as intended - but due to that fact Archetypes will instantiate its own ClassSecurityInfo and populate it with the declarations from the base class that I am trying to override. So the overridden settings are all overwritten again by the base class declaration. My question is, what is the reasoning behind deleting the ClassSecurityInfo object from the class after it has been read the first time? How can this be implemented in a sane way so that custom security declarations can be retained? My understanding (and the way we use it when monkey patching for instance) is that whenevery you apply new security to a class, you create a new ClassSecurityInfo on it. It only defines new stuff to do. The real synthesized security is still stored in __ac_permissions__. class C(SimpleItem): security = ClassSecurityInfo() security.declareProtected(...) def foo(): ... InitializeClass(C) then later on: security = ClassSecurityInfo() C.security = security security.declareProtected(...) C.newmethod = something InitializeClass(C) Anyway that's what I do. I never relied on a preexisting C.security.

Well, you are using __dict__, which you aren't supposed t odo for new
style classes, which FactoryDispatchers now seem to be.
This code:
if not hasattr(pack, '_m'): pack._m=fd.__dict__
fd.debug_compile = debug_compile
fd.debug_compile__roles__ = ('Manager',)
Goes around that, by setting the attributes on the original object
instead of trying to manipulate the dicts directly. But I don't
understand what you are trying to do, so I don't know if it's a good
idea.

[Zope] Problem with links containing non-ascii characters in StructuredText
Hi,
I have a problem getting links to function in StructuredText when they
have non-ascii characters in the title.
- This will render as a link: Zope website:http://zope.org/
- This will render literally: Zöpe website:http://zope.org/
[Notice the diaeresis in the second case.]
This can of course be solved by using html entities like 'ouml;'.
But I have just started using utf-8 so I don't have to bother myself
with writing html entities. There is probably a Python method that
can translate 'ö' into 'ouml;', but I would like the resulting html
code to be humanly readable utf-8 as well. I wouldn't mind iso-8859-1
as that's what it basically is in my case (I'm Dutch) but utf-8 seems
the way to go.
Anyway, here is a script that illustrates the problem. It has some
extra non-ascii characters thrown in just to show that these
characters don't give any problems outside of the links.

That last failed link is obviously not as it should be. Does anyone
know a solution? I failed to find one with Google.
I wondered if it had to do with the diaeresis specifically, but the
same thing goes wrong with e.g. 'Zópe'.
